Physical Characteristics

Body shape

compressed

Coloration

Highly variable, typically a base color of green, yellow, or orange, with 4-7 prominent dark vertical bars or stripes across the body. The head may also have similar markings. Fins are often translucent or match the body coloration.

Scale type

cycloid

Mouth position

superior

Distinctive features

Compressed body, Prominent vertical dark bars/stripes, Large, upward-pointing eyes, Fused pelvic fins forming a suction cup-like disc, Absence of scales on the head and nape

Dorsal fin

Two dorsal fins; the first dorsal fin has 6 spines, and the second dorsal fin has 1 spine and 8-10 soft rays. The two fins are typically separate.

Tail fin

Rounded caudal fin.

Pectoral fin

Pectoral fins are relatively large and rounded, with 17-19 rays.

Identification Tips

1. 1

   Body Pattern

   Look for the distinct vertical dark bars or stripes on a green, yellow, or orange body. The number and prominence of these bars can help distinguish it from other Gobiodon species.

2. 2

   Habitat Association

   Always found nestled within the branches of live branching corals, particularly Acropora. This strong association is a key identifier.

3. 3

   Body Shape

   Its compressed, somewhat flattened body is typical for the genus, allowing it to fit snugly between coral branches.
